    Just got all my engine casings back from the powder coaters having fixed some accident damage and now I’ve come unstuck when re-fitting the clutch cover.

    The clutch release shaft arm inside the clutch cover requires two cylindrical bearings but I can’t see how these bearings are supposed to be seated. I’ve tried fitting them in the top and bottom parts of the cylinder housing that holds the shaft arm but they won’t go and I don’t want to force them and end up getting them stuck.

    Any help greatly appreciated.

    Hopefully this makes it clearer.

    You can see the mechanism shaft. It looksto me as if one of the bearings should sit in the recess at the bottom of the shaft and the other in the recess at the top of the shaft but they won't go in for me with just hand pressure. Was going to try a bit of fresh oil and giving them a gentle whack with something.

    Makes it much easier dang.
    Yes, the needle race bearings do sit top & bottom (you will see an associated wider section on the actuator shaft at those two points).
    There is an oil seal above the upper one, and (iirc) a thrust washer above that.

    Fwiw I would perhaps try putting the casing in an oven for 10 mins, then remove it (with oven gloves or similar) & see if the expansion is enough to enable the cold bearing races to be slotted in to place.

    Good idea. Thank you. Will try that.

    So you think at the bottom of the shaft you have the seal then the bearing then the washer? I’m almost certain that when I took it apart the washer was between the seal and the bearing. Wish I’d taken a photo at the time.

    The washer is outside of the seal.
    On reflection I am certain of this, because when you remove the actuator shaft from a complete casing the washer is on the removed shaft along with the rotation spring.
    If it were inside of the oil seal, it would be captive.

    Thanks StMarks.

    Still can’t manage to fit the bearings anywat. I tried heating up the casing in the oven despite my wife’s disapproval but unfortunately it made no difference.

    I’m close to throwing in the towel and taking it to Carl Rosner.

    Did it!

    There’s something to be said for brute force and ignorance. I was ignorant and they went in with some brute force - using a hammer and punch.
